The sample size that will make the Alex's claim true is option E. 35.
What is Confidence Interval?Confidence interval in statistics is defined as the certain range of values that you estimate for the unknown parameter lies within.
This means that, if you do your experiment more than once and do resampling, then this is the percentage that the parameters falls within a range.
Sample size of Sasha = 30
She took a confidence interval of 95%.
Alex claims he can construct a confidence interval that is narrower by changing the sample size but keeping all other things the same.
The relation between the sample size and confidence interval is that when the size of sample increases, the confidence interval becomes narrower.
So if the Alex's claim has to be true, sample size must increase.
He can use sample size of 35.
Hence the correct option is E.

Find the surface area of a cylinder
whose radius is 5 cm and whose
height is 10 cm.
Answer:-Given:-[tex] \bullet [/tex] Radius of a cylinder (r) is 5 cm
[tex] \bullet [/tex] Height of a cylinder (h) is 10 cm
To Find:-The surface area of a cylinder
Solution:-We know the formula of surface area of a cylinder is –
[tex] { \boxed{\rm \red {2πr² \: + \: 2πrh}}} [/tex]So, putting the value of r = 5 cm and h = 10 cm we get,
2πr(r + h) = 2 × [tex] \frac{22}{7} [/tex] × 5(5 + 10)
= [tex] \frac{220}{7} [/tex](5 + 10)
= [tex] \frac{220}{7} [/tex] × 15
= [tex] \frac{220 \: × \: 15}{7} [/tex]
= [tex] \frac{3300}{7} [/tex]

Model with mathematics. Hamid has read 60 pages of the book
he will be using for a book report. If he reads 45 pages per hour, how
many hours will it take him to read at least 375 pages of the book?
Define a variable, and then write and solve an inequality to represent
this situation. Graph the solution on a number line.
Answer:
Hamid will take 8 hours and 20 minutes to read 375 pages of the book.
Step-by-step explanation:
Given that Hamid has read 60 pages of the book he will be using for a book report, if he reads 45 pages per hour, to determine how many hours will it take him to read at least 375 pages of the book the following calculation must be done:
375/45 = X
8.3333 = X
0.333 x 60 = 20
Thus, Hamid will take 8 hours and 20 minutes to read 375 pages of the book.
